This is a lovely example of the large, Swivel brooches. One could wear the hair work to be shown, or they could swivel the peace around and show the photo of a loved one. This is a large piece, and the hair work is wonderful. I can see a Civil War Enactment participant wearing this, or a docent in a period home. It is not gold, but pinchbeck--that wonderful English metal that looks and wears like gold, but isn't. In fact, pinchbeck often looks better than gold. This piece is in excellent condition, and it weighs 45.15 grams. It measures 2 and 1/2 inches long, and 2 and 1/8 inches wide. It is circa 1860-1870. Please forgive the glare on the photo: There is no damage.
